Joe, you are correct in the "creep". 

I should have been more specific in the application. I use a hypo needle and hit a single drop to the bass of the screw and apply again. Not much and it shouldn't get any further than the screw and barrel. As with anything else, it's all about how you use it. Two aspirin will help your headache, a bottle will probably kill you :-)
